Animation nodes - animate object attribute/transform with Object ID Key and Sound Evaluation
Your example index list is $(10,14,3,\dots)$, which means you want the 10th object to scale based on the first frequency band, the 14th object to scale based on the second frequency band, the 3rd object to scale based on the third frequency band and so on. So, if we left the sound data untouched and reordered the object list such that the first element becomes the 10th object, the second element becomes the 14th object and so on, we will get the desired effect. The same reordering should be done to the object's locations. This reordering is easily achieved by getting the objects and their locations at the ID indices:
